I bought a few of these. The glass is actually three panes of glass fixed together. Some of the frames had glass that was fine, one had dust/particles between the panes that couldn't be cleaned off. The back of the frame is fixed in place by metal studs that you have to manually pry open to get the backing out and back in, and when I popped a few up, the wood cracked/dented the frame back. So, pretty cheap material, kinda irritating design. That being said, you can't tell that from the front of the frame, it looks great otherwise.
